Make the equation: CL2-Ca (OCl) 2-HClO-HCl-Cl2
| February 14, 2021 | education
By condition, the following chain of transformations is given:
Cl2 → Ca (OCl) 2 → HClO → HCl → Cl2.
1.2Cl2 + 2Ca (OH) 2 = CaCl2 + Ca (ClO) 2 + 2H2O (without heating).
2. Ca (ClO) 2 + H2O + CO2 = CaCO3 ↓ + 2HClO.
3.3HClO → 2HCL + HClO3 (when heated, ≈ 50 °).
4. All methods of obtaining free chlorine are based on an oxidation reaction. MnO2 (and others) can be taken as an oxidizing agent.
4HCL + MnO2 = Cl2 ↑ + MnCl2 + 2H2O. This is a laboratory method for producing pure chlorine.
